#include <bits/stdc++.h>
using namespace std;
void solve(){
int n,sum=0,ans=0;
string s;
cin>>n>>s;
for(int i=0;i+3<n;i++) if(s.substr(i,4)=="CCPC") sum++;
for(int i=0;i<=n;i++) for(int o:{0,1}){
int v=sum;
for(int j=max(i-3,0);j<i&&j+3<n;j++) v-=s.substr(j,4)=="CCPC";
for(int j=max(i-3,0);j<=i&&j+3<=n;j++) v+=s.substr(j,i-j)+(o?"C":"P")+s.substr(i,3-i+j)=="CCPC";
ans=max(ans,v);
}
cout<<ans<<"\n";
}
int main(){
cin.tie(0)->sync_with_stdio(0);
int t;
cin>>t;
while(t--) solve();
return 0;
}
这程序好像有点Bug，我给组数据试试？
